I randomly thought of a position similar to this and so I couldn't sleep. Yes it was that interesting to me so I got the position on a chess board and tried to tailor it so it functioned as a real puzzle despite the unusual position.
The 'main' moves are the top engine lines and if you go to the other moves, you can see that doing other moves that may seem logical result in a faster checkmate.
After some time I made this! Please try it and have fun with it
